One of the particular energies an electron can have in an atom. Higher energy levels are further from the nucleus.

Revise: Structure of an AtomElectrons are arranged at particular distances from the nucleus, called energy levels. A lower energy level is closer to the nucleus; a higher energy level is further away. An electron in a higher level has more energy than one in a lower level.
Paper 5, Paper 6
One of the allowed energies an electron can have in an atom; in the Bohr model, each level corresponds to a particular orbital distance from the nucleus.
Link absorption to a higher energy level and emission to a lower energy level; name electromagnetic radiation in your explanation.
For Bohr’s improvement, state that electrons occupy fixed energy levels at particular distances from the nucleus—not simply that electrons orbit.

In 1913, Niels Bohr developed the nuclear model further. He proposed that electrons could occupy only particular orbits at fixed distances from the nucleus. These orbits corresponded to distinct energy levels, with higher energy levels farther from the nucleus.
